Specification of Letters Patent. Patented NOV. 30, 1909.

Application filed April 21, 1909. Serial No. 491,290.

To all whom 'it may concern:

Be it known that I, JOSHUA Srouenno, a citizen of the United States,residing at Port Wing, in the county of Bayfield and State of Wisconsin,have invented certain new and useful Improvements in ToyFlying-Machines, of which the following is a specification.

specific structure shown and described may be made within the scope ofthe claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side view of the devicc,Fig. 2 is a view of the inner sideof the rigid propeller, Fig. 3 is a similar view of the outer side ofthe revoluble propeller, Fig. 4 is a bottom view of the device, Fig. 5is a detail side view of the check means in engaged position, Fig. (3 isa similar view showing it in disengaged position.

Referring to the drawings, there is shown a toy comprising a centralshaft 10 having secured rigidly to one end the propeller 11 which may beof any suitable type, but as shown is stamped integrally from one sheetof metal preferably aluminum, and has four radial blades 13. Thiscomprises the forward or top end of .the toy, and secured to thepropeller 11, there is a helical spring 13 engaged loosely around theshaft 10 and connected similarly to a second propeller 14 carriedrevolubly on the shaft and held against inward sliding movement by meansof a collar 15 secured to the shaft. The manner in which the springisengaged with the propellers is by forming hooks in theopposite ends ofthe spring which are engaged through a simple perforation formedcentrally of the blades. The lower or rear propeller 14 carries upon itsouter face a series of'ratchet ridges 17 stamped therein. The

- lower end of the shaft 10. is extended below the propeller 14;, andturns upwardly to form a U-shaped portionlS which serves as a handle forthe holding of the device during its winding and release. A spaceddistance from the vane 14 the upwardly extended portion of the wireforming the shaft 18 is turned laterally forming a shoulder as at 19 atright angles to the plane of the U-shaped portion, thence horizontallyoutwardly at right angles to the shoulder and formed into a helix 20,from whence it extends inwardly again, past. the axis of the shaft 10and upwardly, its end portion engaging resiliently against the ratchetportions 17. The portion extending from the helix 20 to the extremity ofthe wire is called the trigger portion and intern'iediately of itslength there is formed an eye 23, in which there is engaged a string 24serving as a restraining and guiding member, and also to release thetrigger as will be subsequently described. The helix 20 is so formed asto normally throw the trigger portion upwardly above the shoulder 19,and against the horizontal portion designated B on the drawings. Thehelix is also so formed that the trigger portion presses outwardlytoward the U-shapcd portion 18, and against the portion B, so that whenpulled downwardly the trigger slides 'nwardly and under the shoulder 19,holding the trigger permanently out ofengagement with the ratchet on thepropeller 11,.

until properly set.

In use, when it is desired to wind the device up the propeller 1-1 ispreferably grasped in the left hand from the inside, while the righthand is used to rotate the shaft 10 by manipulation of the handleportion 18, or by means of the forefinger pressed against the helix 20.\Vhcn it is desired to set the machine in flight, the handle portion 18is grasped between the thumb and forefinger of onehand and the devicepointed in the direction it is desired for it to fly and the string 23pulled, which releases the trigger. The device is then immediatelyreleased when it will fly in the direction pointed. The string 24 maybeheld by the operator if desired, to guide the toy and to prevent itfrom doing damage 01' becoming lost. If the string is released it servessomewhat as a guiding rudder or tail.

Itwill be seen from the foregoing that a very simple toy is providedcomprising but four elements, each of which is of the simplestcharacter, and adapted to be manufactured at the lowest possible cost.

What is claimed is:

1. A toy of the class described, comprising a shaft, a propeller securedto one end thereof, a second propeller engaged revolubly upon the shaft,resilient means connecting the propellers, a ratchet portion on thesecond named propeller, said shaft having one extremity bent to engageresiliently against the ratchet portion to hold the second namedpropeller against rotation at times, and means for holding the shaft outof such engagement at times.

2. In a device of the class described, a propeller stamped from sheetmaterial, a concentric series of ratchet teeth stamped therein, a shaftengaged revolubly therethrough, a second propeller carried rigidly atone end of the shaft spaced from the first propeller, and a resilientmember secured to the propellers, one end of the shaft being bentinwardly to engage the ratchet teeth at times, and means for holding theshaft out of engagement with the ratchet teeth at other times.

3. A toy of the class described comprising a shaft, a propeller rigidlysecured to one end thereof, said propeller being stamped integrally fromsheet material, a second similar propeller engaged revolubly upon I theshaft, a helical spring connecting the propellers, a ratchet portioncarried by the second propeller, said shaft having one extremit extendedthrough the last named propel er and turned inwardly, its extremitybeing disposed resiliently against the ratchet portion to hold thesecond propeller against rotation at times, and means for holding theextremity of the shaft out of such engagement at times.

4. A toy of the class described comprising a wire shaft, a propellersecured to one end thereof, a second propeller revolubly engagedinwardly of the first, a resilient member secured to the two propellers,ratchet portions carried on the outer face of the second propeller, theadjacent end of the shaft being extended through the propeller andturned backwardly to a point a spaced distance from the propeller toform a handle portion, the end portion being bent out wardly and thenceinwardly to form a trigger, its extremity being turned upwardly toengage the ratchet portion upon the adjacent propeller, the outwardlyturned portion of the wire having a projection formed therein adapted toengage over the trigger at times to hold it out of engagement with theratchet portion, and means for with drawing said trigger from engagedposition.

In testimony whereof I affix my signature, in presence of two witnesses.
